Average age of SpineCor group was 12.8±1.5 and average follow up period was 25±10.6 months. In rigid brace, the group average age was 12.2±1.3 and average follow up period was 23±6.7months. There were no differences between groups according to age, gender, height, T1-Cx distance, Cobb angles, gibbosity before brace treatment initiated. In both groups, height and T1-Cx distance increased and there were no difference. Cobb angle decreased 1.5° in SpineCor group and increased 1.1 ° in rigid brace group (p=0,137). Gibbosity decreased 0.6° in SpineCor group and increased 0.3° in rigid brace group (p=0,086). According to SRS-22 questionnaire, SpineCor brace patients’ pain, self image and activity/function scores were statistically better than rigid brace patients’ scores, while mental health and satisfaction from treatment scores were similar.
